볼릭시바트(Volixibat) : 판매 예측 및 시장 규모(2034년)

Key Factors Driving Volixibat Growth

• Positive Phase IIb PSC data substantially de-risked the program

In May 2026, Mirum announced that the Phase IIb VISTAS study in PSC achieved its primary endpoint, demonstrating clinically meaningful reductions in cholestatic pruritus (itch). Patients receiving volixibat experienced a 2.72-point reduction in itch scores compared with 1.08 points for placebo, with 55.6% achieving at least a two-point improvement. Serum bile acid reductions were also statistically significant. These results strongly support potential regulatory filings and commercial viability in PSC.

• PSC and PBC represent major unmet-need orphan markets

PSC currently has no approved therapies globally, while many PBC patients continue to experience severe itch despite existing treatments. Mirum estimates approximately 24,000 PSC patients and 140,000 PBC patients in the United States alone. Because cholestatic pruritus severely impacts quality of life, effective symptom control could drive rapid physician adoption and premium orphan-drug pricing.

• Breakthrough Therapy Designation may accelerate development and adoption

Volixibat has received FDA Breakthrough Therapy Designation for cholestatic pruritus in PBC. This designation reflects both the seriousness of the condition and the encouraging efficacy observed in earlier trials. Regulatory support may accelerate review timelines, improve physician awareness, and strengthen reimbursement prospects upon approval.

• Strong efficacy across multiple patient-relevant endpoints enhances differentiation

Beyond itch reduction, volixibat has demonstrated improvements in fatigue, sleep quality, serum bile acids, and inflammatory biomarkers such as IL-31. In the Phase IIb VANTAGE study in PBC, the combined dose group achieved a statistically significant 3.78-point reduction in itch scores (p<0.0001), while 70% of treated patients achieved >=50% reductions in serum bile acids. Rapid onset of action, with responses observed as early as week 1, may further differentiate volixibat from competing cholestatic therapies.

• Validated IBAT inhibitor class reduces commercial and regulatory risk

The IBAT inhibitor class is already clinically validated through Mirum's approved drug maralixibat (LIVMARLI) and other approved agents in rare cholestatic disorders. Because physicians are increasingly familiar with bile acid transporter inhibition and its mechanism in reducing toxic bile acid accumulation, volixibat may benefit from faster clinical uptake and lower educational barriers. The main adverse event profile-primarily mild-to-moderate diarrhea-also appears manageable and consistent with the class.

• Potential blockbuster opportunity with launch expected around 2027

Following the positive PSC Phase IIb readout, multiple analysts described volixibat as a potential "$1B+ commercial opportunity." Investor commentary after the VISTAS results suggested that approval pathways are becoming increasingly realistic, with some analysts projecting potential launch timing around 2027. Because volixibat is being developed simultaneously in PSC and PBC, dual-indication expansion could significantly increase peak sales potential. Continued success in registrational studies may position volixibat as one of the leading therapies in adult cholestatic liver disease.

Volixibat Recent Developments

In May 2026, Mirum Pharmaceuticals, Inc. announced the primary endpoint was met in the VISTAS Phase IIb study evaluating Volixibat, an investigational oral ileal bile acid transporter (IBAT) inhibitor, in patients with primary sclerosing cholangitis (PSC).

Volixibat Drug Summary

Volixibat is an investigational, orally administered apical sodium-dependent bile acid transporter (ASBT/IBAT) inhibitor developed by Sannova Biotherapeutics and previously by Mirum Pharmaceuticals for the treatment of cholestatic and metabolic liver diseases, including primary sclerosing cholangitis (PSC), nonalcoholic steatohepatitis (NASH), and pruritus associated with cholestatic disorders. By selectively inhibiting ASBT in the terminal ileum, volixibat reduces enterohepatic recirculation of bile acids, thereby increasing fecal bile acid excretion and lowering hepatic bile acid accumulation, which contributes to reduced cholestatic injury, inflammation, fibrosis, and itching. The drug's mechanism also influences lipid and glucose metabolism, supporting its investigation in metabolic liver diseases. Clinical studies have demonstrated reductions in serum bile acid levels, improvements in pruritus symptoms, and favorable effects on liver biomarkers, although gastrointestinal adverse events such as diarrhea and abdominal discomfort have been commonly observed due to increased colonic bile acid exposure. Volixibat has been evaluated in multiple Phase II clinical trials, particularly in PSC and NASH, and continues to be explored as a non-systemic therapeutic option targeting bile acid dysregulation. The report provides Volixibat's sales, growth barriers and drivers, post usage and approvals in multiple indications.
